| 摘要 |
<p>The present invention relates to a multimodal polyethylene resin composition for fibre supporting elements for fibre optic cables having a MFR5 of 0.10 to 1.0g/10 min, a density of 935 to 960 kg/m3 and a flow rate ratio FRR¿21/5? of 30 to 150. These resins can be obtained by a process comprising the treatment of a base resin (C), which comprises a low molecular weight component (A) and a high molecular weight component (B), in the presence of free radical initiators to incorporate long chain branches. Furthermore, the invention relates to an optical fibre supporting element comprising the multimodal polyethylene resin composition and to a fibre optic cable comprising such optical fibre supporting elements.</p> |
